Description

Technical Field

[0001] The invention relates to a braking system, in particular to an automobile brake. Background Art

[0002] At present, automobile brakes refer to components that produce braking force that hinders the movement or movement trend of the vehicle. They can be divided into drum brakes, disc brakes, and disc brakes. Various braking methods can be used, such as predictive braking, emergency braking, and parking brakes. Drum brakes have strong instantaneous braking force, but the braking force drops quickly after heating; disc brakes have good stability, but low braking efficiency; disc brakes are highly technical, and the instantaneous braking force is insufficient, but it can still maintain a good braking effect after heating. Each has its own characteristics. However, the braking force is unbalanced and unstable, which adversely affects the braking effect. Multiple molds need to be made for various specifications, which increases production costs, and braking safety and product quality cannot be effectively guaranteed. Summary of the invention

[0003] The purpose of the present invention is to solve the deficiencies in the prior art and to provide an oblique-insertion automobile brake which is convenient to manufacture and install, has balanced braking force and stable operation.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: an oblique plug-in automobile brake, including a friction plate and a cylinder, wherein the cylinder is an annular cylinder and includes an annular cylinder body, wherein an interconnected piston and piston rod are installed in the annular cylinder body, wherein the piston and the piston rod are both provided with a communicating air intake passage, wherein the piston has a sloped structure and the sloped structure is connected to the friction plate through a top block.

[0005] The slope structure is composed of a plurality of protrusions, and one side of each protrusion has a slope surface connected to the top block. The slope surface of the protrusion is arc-shaped or polygonal. A sealing ring is installed between the piston and the inner wall of the annular cylinder body to form a closed space and a tight fit. An annular cover plate is installed at the bottom of the annular cylinder body, and the outer end of the piston rod extends from the annular cover plate and is equipped with a nut to achieve limiting, which is convenient for braking and limiting, and is firm and reliable. A spring is installed in the annular cylinder body, between the annular cover plate and the piston, or on the piston rod to realize spring energy storage. The piston is ring-shaped and is one piece, the piston rod and the spring are several pieces, the piston rod with an air intake channel is one piece, and the top block is several pieces.

[0006] After adopting the structure of the present invention, the oblique insertion automobile brake has the following advantages compared with the prior art: the structure is more reasonably stressed and the performance is more stable. The spring force of the spring and the piston are inserted obliquely onto the top block through the slope structure of the piston, so that the top block and the friction plate are connected to achieve braking. For this reason, the forces on each component are more balanced and more stable, avoiding the situation where a certain component is subjected to excessive force under extreme conditions and causes damage to the component. The brake has better adaptability and wider application. By adjusting the slope range of the slope structure of the piston, it is easy to manufacture brakes of various specifications and sizes, which can especially meet the brake needs of trucks of various tonnages.

[0009] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0010] Reference Figure 1 , Figure 2 It can be seen that the oblique plug-in automobile brake of the present invention comprises a friction plate 7 and a cylinder. The cylinder is an annular cylinder and comprises an annular cylinder body 1. An interconnected piston 2 and a piston rod 6 are installed in the annular cylinder body 1. The piston 2 and the piston rod 6 are both provided with a connected air intake passage 9. The piston 2 has a ramp structure and the ramp structure is connected to the friction plate 7 through a top block 3. The top block 3 passes through the annular cylinder body 1 and is connected to the friction plate 7. The ramp structure is composed of a plurality of protrusions 11 (the protrusions 11 are evenly distributed around the piston 2 and are three or more pieces, and the protrusions 11 and the piston 2 are integral), and one side of the protrusions 11 has a ramp surface 12 connected to the top block 3 (the top block 3 is also correspondingly three or more pieces). One of the protrusions 11 may also be provided with an air intake passage 9 connected to the piston 2 and the piston rod 6. The ramp surface 12 of the protrusion 11 is arc-shaped or polygonal (quadrilateral or more than quadrilateral polygon).

[0011] A sealing ring 8 (two pieces form a double seal) is installed between the piston 2 and the inner wall of the annular cylinder body 1 to form a closed space and a tight fit. An annular cover plate 5 is installed at the bottom of the annular cylinder body 1, and the outer end of the piston rod 6 extends from the annular cover plate 5 and is equipped with a nut 10 to achieve limiting, which is convenient for braking and limiting, and is firm and reliable. A spring 4 is installed in the annular cylinder body 1, between the annular cover plate 5 and the piston 2, or on the piston rod 6 to achieve spring energy storage. The piston 2 is annular in shape and is one piece, the piston rod 6 and the spring 4 are several pieces, the piston rod 6 with the air inlet channel 9 is one piece, and the top block 3 is several pieces. The annular cylinder body 1, the piston 2 (and the convex block 11), the spring 4, the piston rod 6, the annular cover plate 5, etc. constitute an annular cylinder.

[0012] As shown in the accompanying drawings, the present invention inflates or cuts off the air in the air inlet passage 9 of the piston rod 6, the piston 2 and the bump 11, and utilizes the interaction between the elastic force of the spring 4 and the air pressure in the annular cylinder body 1 to achieve the left and right movement of the piston rod 6, the spring and the piston, and realizes the telescopic movement of the top block 3 through the movement and change of the slope structure of the piston (the bump 11 and its slope surface 12), so that the top block 3 and the friction plate 7 are pressed against or separated to achieve braking or release the brake.
